Product details

Overview

74HCU04S14-13 from Diodes Incorporated is a hex unbuffered CMOS inverter IC with standard push-pull outputs, operating across 2.0V–6.0V supply range. It delivers six independent inverters, each supporting 4mA drive capability at 4.5V, Schmitt-trigger inputs for noise immunity, and logic-level inversion (A → Y̅) in SO-14 package for crystal oscillator buffering and analog inverter applications.

For engineers reviewing the 74HCU04S14-13 datasheet, 74HCU04S14-13 pinout, 74HCU04S14-13 application, or 74HCU04S14-13 equivalent, key selection criteria include supply voltage flexibility (2.0–6.0V), propagation delay (5–21 ns), input hysteresis, ESD robustness (2kV HBM), and SO-14 thermal performance for embedded timing and logic interface designs.

Technical Context

The 74HCU04 implements unbuffered inverter topology-no internal stage buffering-enabling precise analog inverter behavior and low propagation delay. Its Schmitt-trigger inputs provide hysteresis (typ. 0.8V at VCC = 4.5V), improving noise rejection in oscillatory or slow-rising signal environments.

All six gates share identical electrical characteristics: VIH/VIL thresholds scale with VCC (e.g., VIH ≥ 3.6V @ 4.5V), VOH/VOL are load-dependent (VOH ≥ 3.84V @ IOH = –4mA), and power consumption remains ultra-low (ICC ≤ 40μA @ 6V).

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	2.0V to 6.0V - enables single-supply operation across 3.3V and 5V systems without level-shifting.
Propagation Delay (tPD)	5 ns (typ) @ 6.0V, CL = 50pF - supports >20 MHz toggle rates in clock distribution paths.
Output Drive	±4mA @ 4.5V - sufficient to drive multiple CMOS inputs or small capacitive loads directly.
Input Hysteresis	Yes, Schmitt-trigger - eliminates chatter on slow edges; critical for reliable crystal oscillator startup and feedback control.
ESD Protection	2 kV HBM, 1 kV CDM - exceeds JEDEC standards for board-level handling in industrial assembly.
Power Dissipation per Gate	10 pF Cpd @ 1 MHz - ensures sub-100μW static power per inverter at typical frequencies.

Pinout & Package

74HCU04S14-13 is housed in a 14-pin SOIC (SO-14) package with 1.27 mm pitch, 8.53–8.74 mm body length, and 3.80–3.99 mm width. Thermal resistance (θJA) is 125°C/W, suitable for ambient temperatures up to +125°C.

Pin/Terminal	Circuit Role	Design Meaning
1, 3, 5, 9, 11, 13	Data Input (1A–6A)	CMOS Schmitt-trigger inputs accepting 0–VCC logic levels; internally biased for hysteresis.
2, 4, 6, 8, 10, 12	Data Output (1Y–6Y)	Push-pull CMOS outputs sourcing/sinking up to ±4mA; rail-to-rail swing under load.
7	GND	Ground reference for all logic and power domains; must be low-impedance for noise immunity.
14	VCC	Primary power supply input; decoupling capacitor (100nF) required within 5 mm of pin.

Key Features

Feature	Design Value
Unbuffered Inverter Architecture	Enables analog use cases (e.g., Pierce oscillator feedback) with minimal phase shift and no added gate delay staging.
Wide-Voltage Operation (2.0–6.0V)	Eliminates need for separate 3.3V/5V logic families in mixed-supply systems like USB peripherals or legacy industrial controllers.
Schmitt-Trigger Inputs	Provides 0.8V typical hysteresis at 4.5V, rejecting noise spikes <1.2V and ensuring clean transitions on slow RC waveforms.
Low ICC Current (≤40 μA)	Reduces quiescent power in battery-backed real-time clocks or always-on sensor interfaces without compromising speed.

Applications

Crystal Oscillator Circuit

Analog Signal Inversion

Use Scenario: Used as gain element in Pierce crystal oscillator topologies with parallel-resonant quartz crystals (e.g., 1–20 MHz).

IC Role / Device Role / Timing Role: Unbuffered inverter provides phase inversion and gain to sustain oscillation; Schmitt input ensures reliable startup under temperature variation.

Use Value: Eliminates external bias resistors and reduces component count vs. discrete transistor oscillators while maintaining frequency stability.

Use Scenario: Inverting slow-rising analog signals (e.g., thermistor-based voltage ramps or PWM-derived DC references).

IC Role / Device Role / Timing Role: Functions as precision analog inverter with rail-to-rail output swing and defined threshold hysteresis.

Use Value: Replaces op-amp inverter circuits where bandwidth <1 MHz suffices and supply headroom is limited to 2.0–6.0V.

Legacy System Logic Interface

Level Translation Bridge

Use Scenario: Interfacing 5V microcontrollers with 3.3V peripherals in industrial PLC I/O modules.

IC Role / Device Role / Timing Role: Performs voltage-level compatible logic inversion between mixed-voltage subsystems without external resistors.

Use Value: Enables direct connection between 5V TTL outputs and 3.3V CMOS inputs using same device for both directions via dual-rail compatibility.

Use Scenario: Converting 2.0V logic signals (e.g., from low-power sensors) to 6.0V-compatible control lines in motor driver enable circuits.

IC Role / Device Role / Timing Role: Acts as bidirectional level shifter by leveraging wide VCC tolerance and rail-referenced input thresholds.

Use Value: Avoids dedicated level translators; supports asymmetric voltage translation (e.g., 2.0V-in → 6.0V-out) with guaranteed VIH/VIL margins.

Equivalent & Alternatives

The following parts are listed as comparable options for similar hex inverter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74HC04DR	No Schmitt-trigger inputs; standard CMOS thresholds only (VIH = 3.15V min @ 4.5V).	Lacks hysteresis - unsuitable for oscillator or noisy analog inversion; better for pure digital fanout.	Select when noise immunity is not required and lower cost is prioritized over analog functionality.
74LVC04PW,118	Lower VCC range (1.65–5.5V); higher drive (±24mA); no Schmitt inputs.	Optimized for high-speed 3.3V digital buses; incompatible with 6V systems or crystal oscillator biasing.	Prefer for dense PCB layouts needing TSSOP-14 and 3.3V-only operation with stronger drive.

Compared with SN74HC04DR and 74LVC04PW,118, the 74HCU04S14-13 uniquely combines Schmitt-trigger inputs, 6V tolerance, and unbuffered architecture-making it irreplaceable for oscillator design and mixed-voltage analog-digital interfacing where hysteresis and rail flexibility are mandatory.

FAQ

Can 74HCU04S14-13 operate reliably at 2.0V supply?

Yes. The device is fully specified down to 2.0V: VIH ≥ 1.7V, VOL ≤ 0.3V at IOL = 4mA, and tPD ≤ 90ns (max) at CL = 50pF. This makes it suitable for battery-powered systems with brown-out conditions or low-voltage microcontroller peripherals.

Is unused input termination required?

Yes. Per datasheet Note 6, all unused inputs must be tied to either VCC or GND to prevent floating nodes that cause increased ICC, oscillation, or ESD susceptibility. Leaving inputs unconnected risks erratic behavior and elevated power consumption.

What is the maximum capacitive load this device can drive?

At 4.5V supply, the device maintains tPD ≤ 21ns and output swing ≥ 3.84V with CL = 50pF. Driving >100pF increases propagation delay nonlinearly and may degrade VOL/VOH margins; for heavier loads, add series resistance or buffer stages.

Does 74HCU04S14-13 support hot-swap or live-insertion?

No. The device lacks hot-swap protection circuitry. Applying VCC before GND or sequencing power incorrectly may trigger latch-up due to internal parasitic SCR structures. Always follow proper power-rail ramp sequencing (GND first, then VCC) in backplane or modular systems.
